Free Asset Radar x402 Hash API
x402
Free Asset Radar x402 Hash API is a paid API for AI agents from free-asset-radar-x402.besenok2018.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-09-30).
Computes a SHA-256 hash of provided data and returns hex and base64 encodings via an x402-payable edge endpoint

How this service works
Stable edge-hosted x402 utilities for autonomous agents.
Output
A JSON object containing the SHA-256 hash of the input in hex encoding, base64 encoding, and the algorithm name ('sha256'). Example: {"hex":"...","algo":"sha256","base64":"..."}
Example use cases
Content fingerprinting for deduplication
“Hash this document content so I can fingerprint it and detect duplicates in my pipeline: 'The quick brown fox jumps over the lazy dog'”
Data integrity verification in agent workflow
“Compute a SHA-256 hash of this payload so I can verify its integrity later: '{"user":"alice","action":"transfer","amount":100}'”
Checksum generation for file reference
“Give me the SHA-256 checksum in both hex and base64 for the string 'my-unique-asset-id-12345' so I can use it as a stable reference key”
Technical details
Endpoint
GEThttps://free-asset-radar-x402.besenok2018.workers.dev/api/x402/hash?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-use SHA-256 hash computation via the x402 micropayment protocol, particularly in autonomous agent pipelines that already use x402 for payments and need a lightweight cryptographic utility without spinning up dedicated infrastructure. It is ideal for low-volume, on-demand hashing tasks where setting up a local hashing library is impractical.
Side effects
- Missing required input parameters returns an error
- Malformed request body may result in a 400 Bad Request
- Payment not fulfilled via x402 protocol results in a 402 Payment Required response
- Edge worker downtime or cold start may cause transient 5xx errors
- Unsupported input types may produce unexpected hash output
